To do:
Debug Room still exists in this version, as does at least one unused background

Yoshi's Island: Super Mario Advance 3 is the portable port of Super Mario World 2: Yoshi's Island. Having a long full title apparently runs in the family.
Of the four Advance ports, it is the least different from the source material, being an almost completely straightforward port with the only major additions being some new Extra levels and added voice lines from Yoshi's Story.

Unused Graphics

Because it is for the most part a straight port, most if not all of the unused graphics from the original game remain.

Alternate (and strange-looking) versions of the Hint Box. Its expression never changes in-game.

SMA3 QuestionBlockFrames.png

The unused ? Block from the SNES game, now with 3 extra frames lifted from the prototypes.

The original title of the game is still stored in the title screen graphics, with its palette intact.

Unused Sprites

With exception of the Red Bullet Bill, all of the unused sprites and behavior remain unused in this port.

Sprite ID: F1
The Egg Plant variant that spits bubbles, except it doesn't spit bubbles in this port.


Sprite ID: 195
A smaller version of the tilting snowy platform.

Unused Autoscroll Data

Unused Autoscroll Command

There is an autoscroll command that is not used anywhere and is not associated to any sprite, the autoscroller command is as follows:

Note: The first value represents the X coordinate, the second value is the Y coordinate, and the third value is the scrolling speed.

Unused Autoscroll End Command

Autoscroll end command FC is a duplicate of autoscroll end command FF, which is used to stop the autoscroll and locks the screen at the last area the autoscroll moved.

Level Behavior Oddity

Room ID EA (the fourth area of Secret 4: Fight Toadies w/ Toadies) has a unique special behavior where stationary sprites can stand on moving platforms. Bullet Bills Shooters however, are a special case: if the sprite is standing on the right edge of a moving platform, it only appears if you come from the left side. If it is standing on the left edge of a moving platform, it will only appear if you come from the right side of the screen. If it's standing in the middle, it will always appear. Since this room uses an autoscroll that moves the screen from left to right, only the Bullet Bill Shooters placed on the right edge of a platform can be seen.

World 0

Baby Mario is not amused.

While not unused, it's unlikely that any normal player not knowing about this would ever see it. The "World 0" icon can only be seen if you get a Game Over during the intro level, at which point your progress (or lack thereof) is saved.

No equivalent exists in the SNES version, since you are given an infinite number of lives on the intro level. Even setting your lives to zero via cheat code and then getting a Game Over will display only an empty file; the game does not save World 0 to SRAM.

Regional Differences

SMA3 Title Screen

Japan International China
Yay, look at all these cute and cheerful Yoshis! Hooray! Yay, look at... uhm... this abandoned egg? Hooray...? SMA3TitleCh.png

As with the previous game, the graphics designers at NoA must have been out to lunch or something while this game was being localized, leaving us with this uninspired logo outside of Japan. Like the previous Super Mario Advance games, China's is based from the Japanese title screen.

Graphical Differences

To do:
Compare graphics for the Secret stage icons. Final boss Baby Bowser has three fingers in SNES version, four in the GBA version.

All of the graphical differences from the original game apply here as well.

Stage Names

Three of the stages (two being secret stages) have different names in the European English version than in the American English version.
